  1. 16. AN ADAPTIVE CONTROL SYSTEM BASED ON PID, I2PD AND RLS, A SIMULATED DESIGN FOR UAVS

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Johan Gärtner; Philip Johansson; [2017]
    Keywords : RLS; PID Controller; UAV; quadrotor; adaptive control; I2PD; simulation;

    Abstract : During this master thesis an adaptive control system for angular velocity was developed. The approach focuses on radio controlled quadrotors and thereby targets a computational efficient solution. The adaptation is divided into two steps. READ MORE

  3. 17. Passive Inter-modulation Cancellation in FDD System

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Fan Chen; [2017]
    Keywords : Technology and Engineering;

    Abstract : Passive inter-modulation (PIM) shows up when two or more RF signals are mixed together via the nonlinear passive devices. With the rapid development and expansion of the wireless com-munication networks, PIM is recognized as one of the most critical issues. READ MORE

  4. 18. Regression-Based Monte Carlo For Pricing High-Dimensional American-Style Options

    University essay from Umeå universitet/Institutionen för fysik

    Author : Niklas Andersson; [2016]
    Keywords : American options; Monte Carlo; Robust Regression; Quasi Monte Carlo; Importance sampling;

    Abstract : Pricing different financial derivatives is an essential part of the financial industry. For some derivatives there exists a closed form solution, however the pricing of high-dimensional American-style derivatives is still today a challenging problem. READ MORE

  5. 19. Analysis of Activity Recognition and the Influence of Feature Extraction and Selection in an Android Based Device

    University essay from Lunds universitet/Matematik LTH

    Author : Philip Holgersson; Fredrik Åkerberg; [2015]
    Keywords : activity analysis; confusion matrix; data analysis; classification; least squares; features selection; feature extraction; accelerometer; Technology and Engineering;

    Abstract : Tracking activities have lately been very popular in smartphones, which requires that the devices are able to classify activities correctly. Since this type of devices has limitations in both power consumption and computational performance, it is important to keep these factors to a minimum. READ MORE

  6. 20. Convex Optimization Methods for System Identification

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Dino Dautbegovic; [2014]
    Keywords : Mathematical Optimization; Convex Optimization; Least-Squares; LTI-System; System Identification; Inverse System;

    Abstract : The extensive use of a least-squares problem formulation in many fields is partly motivated by the existence of an analytic solution formula which makes the theory comprehensible and readily applicable, but also easily embedded in computer-aided design or analysis tools. While the mathematics behind convex optimization has been studied for about a century, several recent researches have stimulated a new interest in the topic. READ MORE
